[0080] The eyeglass frame molding mold is a tool used to produce eyeglass frames, usually using injection molding technology. It consists of an injection system, mold cavity, cooling system, ejector system and exhaust system, etc., by injecting molten plastic material into the mold cavity, and then quickly cooling and removing the molded eyeglass frame product. These molds usually have complex structures and high precision requirements to ensure the production of high-quality eyeglass frame products.

[0081] The eyeglass frame forming molds in the related art are mostly integrated eyeglass frame molds. Integrated eyeglass frame molds can only produce eyeglass frames of specific sizes and shapes. If more sizes and shapes of eyeglass frames need to be produced, different integrated eyeglass frame molds need to be produced to produce different eyeglass frames, which requires wasting more materials to produce different integrated eyeglass frame molds.

[0082] Based on this, in order to improve the problem in the related art that when there is a demand for producing more eyeglass frames, more eyeglass frame forming molds need to be produced; and when the eyeglass frame forming mold is partially damaged, the eyeglass frame forming mold needs to be replaced as a whole, which wastes materials, the embodiment of the present application provides the following solution.

[0083] Please also read Figures 1 to 5 and Figure 7 The embodiment of the present application provides a spectacle frame forming mold 100, comprising an assembly box 10, a mold modular component 20, a first connecting mechanism 70 and a second connecting mechanism 80, wherein:

[0084] The assembly box 10 has a first space 11 and at least two first connection parts 50 .

[0085] The mold modular assembly 20 is arranged in the first space 11; the mold modular assembly 20 includes at least two modular molds 21, the modular mold 21 has a cavity for forming at least part of the eyeglass frame, and the modular mold 21 has a first connecting and fitting portion 30; among two adjacent modular molds 21, one modular mold 21 has a second connecting portion 60, and the other modular mold 21 has a second connecting and fitting portion 40.

[0086] The first connection mechanism 70 is movably disposed on the first connection matching portion 30 .

[0087] The second connection mechanism 80 is movably disposed on the second connection matching portion 40 .

[0088] Among them, the modular mold 21 can be accommodated in the first space 11, and can be detachably connected to the first connecting part 50 through the first connecting mechanism 70; among two adjacent modular molds 21, one modular mold 21 can be detachably connected to the second connecting part 60 of the other modular mold 21 through the second connecting mechanism 80.

[0089] It can be understood that the assembly box 10 is a box-shaped structure having a space for accommodating a spectacle frame forming mold 100 composed of a plurality of mold modular assemblies 20, for example, it can be a metal box-shaped structure with an open space. The modular molds 21 in the mold modular assembly 20 can be adapted to each other and connected and fixed to each other through the second connecting mechanism 80. The modular mold 21 and the assembly box 10 are connected and fixed through the first connecting mechanism 70. The first connecting mechanism 70 is a mechanism for connecting and disconnecting the assembly box 10 and the mold modular assembly 20; the second connecting mechanism 80 is a mechanism for connecting and disconnecting each modular mold 21. The first connecting portion 50 is configured as a component that can cooperate with the first connecting mechanism 70. When the assembly box 10 and the modular mold 21 are connected through the first connecting mechanism 70, the first connecting portion 50 can partially accommodate the first connecting mechanism 70 and fix the first connecting mechanism 70; the second connecting portion 60 is configured as a component that can cooperate with the second connecting mechanism 80. When the modular molds 21 are connected through the second connecting mechanism 80, the second connecting portion 60 can partially accommodate the second connecting mechanism 80 and fix the second connecting mechanism 80.

[0090] As can be seen from the above, the eyeglass frame molding mold 100 provided in the embodiment of the present application, by providing an assembly box 10 having a first space 11 and at least two first connecting parts 50, a mold modular component 20 including at least two modular molds 21, a first connecting mechanism 70 and a second connecting mechanism 80, the modular mold 21 can be accommodated in the first space 11, and can be detachably connected to the first connecting part 50 through the first connecting mechanism 70, and one of the two adjacent modular molds 21 can be detachably connected to the second connecting part 60 of the other modular mold 21 through the second connecting mechanism 80, which can improve the connection stability of the mold modular component 20 in the assembly box 10, and can make the positions of the modular molds 21 relatively stable before preheating. The mold modular component 20 having multiple modular molds 21 can meet the needs of different groups of people for different types of eyeglass frames by assembling different modular molds 21 to form an eyeglass frame molding mold 100. Before the eyeglass frame molding mold 100 is injection molded, the corresponding modular mold 21 can be selected according to actual needs, so that different eyeglass frames can be manufactured and the use of materials can be reduced.

[0091] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5The first connecting portion 50 includes a first locking portion 51 and a first locking space 53. The first locking portion 51 is detachably arranged on a side of the first locking space 53 close to the modular mold 21. The first locking portion 51 is provided with a first locking hole 52 connected to the first locking space 53; the first connecting mechanism 70 can be partially penetrated through the first locking hole 52 and extend into the first locking space 53, and abut against a side of the first locking portion 51 close to the first locking space 53, so as to be detachably connected to the first connecting portion 50.

[0092] It can be understood that the first stopper 51 is a structure that can abut against at least a portion of the first connection mechanism 70 to limit at least a portion of the first connection mechanism 70 in the first stopper space 53, and can be, for example, a plate-shaped structure, a rod-shaped structure, a frame structure, etc., but is not limited thereto. For example, the first stopper 51 can be placed on a side of the first stopper space 53 close to the modular mold 21 by a detachable connection such as a snap connection, a screw connection, or a threaded connection. The opening of the first stopper space 53 can be larger than the first stopper hole 52.

[0093] In this way, the first connection mechanism 70 can extend to the inside of the first stop space 53 and abut against the side of the first stop portion 51 close to the first stop space 53, and connect the modular mold 21 with the assembly box 10, which can not only improve the reliability of the connection between the modular mold 21 and the assembly box 10, but also reduce the distance between the modular mold 21 and the assembly box 10, which is conducive to the fit between the two to increase the contact surface of the two and improve the connection stability, and is conducive to saving space. The first connection portion 50 is provided as a first stop portion 51, a first stop space 53 and a first stop hole 52. Compared with the integrated first connection portion 50, the first connection portion 50 can be divided into two parts for manufacturing, one part is used to manufacture the first stop portion 51 and the first stop hole 52 at the same time, and the other part is used to manufacture the first stop space 53. By manufacturing the above two parts separately, the manufacturing rate can be accelerated, the manufacturing accuracy can be increased and the manufacturing difficulty can be reduced.

[0094] Optionally, the first connecting portion 50 is disposed on an inner wall of the assembly box 10 .

[0095] Compared with the first connection portion 50 being arranged on the lower side wall of the assembly box 10, the first connection portion 50 being arranged on the inner side wall of the assembly box 10 can make the connection between the assembly box 10 and the modular mold 21 more stable, and can reduce the possibility that the modular mold 21 is detached from the assembly box 10 due to the force along the depth direction of the assembly box 10.

[0096] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 7The second connecting portion 60 includes a second locking portion 61 and a second locking space 63. The second locking portion 61 is detachably arranged on a side of the second locking space 63 close to another modular mold 21. The second locking portion 61 is provided with a second locking hole 62 connected to the second locking space 63; the second connecting mechanism 80 can be partially penetrated through the second locking hole 62 and extend into the second locking space 63, and abut against a side of the second locking portion 61 close to the second locking space 63, so as to be detachably connected to the second connecting portion 60.

[0097] It can be understood that the second stopper 61 is a structure that can abut against at least a portion of the second connection mechanism 80 to limit at least a portion of the second connection mechanism 80 in the second stopper space 63, and can be, for example, a plate-shaped structure, a rod-shaped structure, a frame structure, etc., but is not limited thereto. For example, the second stopper 61 can be placed on a side of the second stopper space 63 close to the connected modular mold 21 by a detachable connection such as a snap connection, a screw connection, or a threaded connection. The opening of the second stopper space 63 can be larger than the second stopper hole 62.

[0098] In this way, the second connection mechanism 80 cooperates with the second stopper 61 of the second connection part 60, so that the second stopper 61 can clamp the second connection mechanism 80. This connection mechanism can make the connection of each modular mold 21 tighter. The second connection part 60 is provided with the second stopper 61, the second stopper space 63 and the second stopper hole 62. Compared with the integrated second connection part 60, the second connection part 60 can be manufactured in two parts, one part is used to manufacture the second stopper 61 and the second stopper hole 62 at the same time, and the other part is used to manufacture the second stopper space 63. By manufacturing the above two parts separately, the manufacturing rate can be accelerated, the manufacturing accuracy can be increased and the manufacturing difficulty can be reduced.

[0099] In some embodiments, please refer to Figure 3 and Figure 7 The first connecting fitting portion 30 has a first assembly space 31, the first connecting mechanism 70 is movably arranged in the first assembly space 31, and a first enclosed space 32 is formed between the inner wall of the first assembly space 31 and the first connecting mechanism 70, and a first expansion medium 33 is arranged in the first enclosed space 32; the first expansion medium 33 is used to expand and expand when the temperature rises, and push the first connecting mechanism 70 to move toward the first stopping space 53 and partially extend out of the first assembly space 31, so that the first connecting mechanism 70 is connected to the first connecting portion 50, and is used to shrink and shrink when the temperature drops, and drive the first connecting mechanism 70 to move toward the first enclosed space 32 and move out of the first stopping space 53, so that the first connecting mechanism 70 is separated from the first connecting portion 50.

[0100] It can be understood that the first assembly space 31 can completely accommodate the first connection mechanism 70, and the cooperation between the first assembly space 31 and the first connection mechanism 70 can be a transitional cooperation. The first expansion medium 33 is a medium that can expand and increase in volume after being heated, and can shrink in volume after being cooled. The vaporization point of the first expansion medium 33 is higher than the room temperature (20 to 25 degrees Celsius) and lower than the temperature of the injection liquid (for example: the temperature range of polycarbonate (PC) during injection molding is 250 to 320 degrees Celsius). For example, the first expansion medium 33 can be water, alcohol, carbon dioxide gas, etc.

[0101] In this way, when the eyeglass frame forming mold 100 composed of the assembly box 10 and each modular mold 21 at the corresponding position is preheated, the first expansion medium 33 expands and increases in volume after being heated, so that a pressure difference is generated between the first enclosed space 32 and the first stop space 53, and the first connection mechanism 70 is partially pushed into the first stop space 53 under the action of the pressure difference, so that the first connection mechanism 70 is connected to the first connection part 50. When the injection molding liquid in the cavity of the eyeglass frame forming mold 100 is cooled and molded, the first expansion medium 33 shrinks in volume, so that a pressure difference is generated between the first enclosed space 32 and the first stop space 53, and the first connection mechanism 70 is pushed out of the first stop space 53 under the action of the pressure difference, so that the connection between the first connection mechanism 70 and the first connection part 50 is disconnected. The connection between the assembly box 10 and the modular mold 21 can be linked to the change in temperature. When the temperature rises, the assembly box 10 is connected to the modular mold 21; when the temperature drops, the assembly box 10 is disconnected from the modular mold 21. Furthermore, when the eyeglass frame molding mold 100 is preheated, the first expansion medium 33 can also automatically expand due to the heat. When the eyeglass frame molding mold 100 is cooled after injection molding, the first expansion medium 33 can also automatically cool down and shrink. There is no need for manual or additional temperature control components to heat or cool the first expansion medium 33, which can effectively improve the degree of automation of connecting and fixing the mold modular component 20 and the assembly box 10.

[0102] In some embodiments, please refer to Figure 4 and Figure 7The second connecting fitting portion 40 has a second assembly space 41, the second connecting mechanism 80 is movably arranged in the second assembly space 41, and a second enclosed space 42 is formed between the inner wall of the second assembly space 41 and the second connecting mechanism 80, and a second expansion medium 43 is arranged in the second enclosed space 42; the second expansion medium 43 is used to expand and expand when the temperature rises, so as to push the second connecting mechanism 80 to move toward the second stopping space 63 and partially extend out of the second assembly space 41, so that the second connecting mechanism 80 is connected to the second connecting portion 60, and to shrink and shrink when the temperature drops, so as to drive the second connecting mechanism 80 to move toward the second enclosed space 42 and move out of the second stopping space 63, so that the second connecting mechanism 80 is separated from the second connecting portion 60.

[0103] It can be understood that the second assembly space 41 can completely accommodate the second connection mechanism 80, and the cooperation between the second assembly space 41 and the second connection mechanism 80 can be a transitional cooperation. The second expansion medium 43 is a medium that can expand and increase in volume after being heated, and can shrink in volume after being cooled. The vaporization point of the second expansion medium 43 is higher than the room temperature (20 to 25 degrees Celsius) and lower than the temperature of the injection liquid (for example: the temperature range of polycarbonate (PC) during injection molding is 250 to 320 degrees Celsius). For example, the second expansion medium 43 can be water, alcohol, carbon dioxide gas, etc.

[0104] In this way, when the eyeglass frame forming mold 100 composed of the assembly box 10 and each modular mold 21 in the corresponding position is preheated, the second expansion medium 43 expands and increases in volume after being heated, so that a pressure difference is generated between the second enclosed space 42 and the second stop space 63, and the second connection mechanism 80 is partially pushed into the second stop space 63 under the action of the pressure difference, so that the second connection mechanism 80 is connected to the second connection part 60. When the injection molding liquid in the cavity of the eyeglass frame forming mold 100 is cooled and molded, the second expansion medium 43 shrinks in volume, so that a pressure difference is generated between the second enclosed space 42 and the second stop space 63, and the second connection mechanism 80 is pushed out of the second stop space 63 under the action of the pressure difference, so that the connection between the second connection mechanism 80 and the second connection part 60 is disconnected. The connection between each modular mold 21 can be linked to the change of temperature. When the temperature rises, the modular molds 21 are connected; when the temperature drops, the connection between each modular mold 21 is disconnected.

[0105] Optionally, in some embodiments, see Figure 3 , Figure 5 and Figures 9 to 11 The first connecting mechanism 70 includes a first push rod 71 , a first rotating shaft 73 , a first connecting member 72 and a first spring 74 .

[0106] One end of the first push rod 71 is movably arranged in the first assembly space 31, and a first enclosed space 32 is formed between the inner wall of the first assembly space 31 and the first push rod 71; the other end of the first push rod 71 is provided with a first installation notch 710, and the first installation notch 710 passes through the end face and at least one side face of the first push rod 71.

[0107] The first rotating shaft 73 is located in the first installation notch 710 and connected to the inner wall of the first installation notch 710 .

[0108] One end of the first connecting member 72 is rotatably connected to the first push rod 71 via a first rotating shaft 73 .

[0109] One end of the first spring 74 is connected to the first push rod 71 , and the other end of the first spring 74 is connected to the first connecting member 72 .

[0110] Among them, the first connecting member 72 can be passed through the first locking hole 52 and extend into the first locking space 53, and under the action of the first spring 74, it rotates to abut against the side of the first locking portion 51 close to the first locking space 53, so that the first connecting mechanism 70 and the first connecting portion 50 can be detachably connected.

[0111] It can be understood that the cooperation between the first push rod 71 and the first assembly space 31 can be a transitional cooperation, and the first push rod 71 can move along the first assembly space 31 toward the first stop hole 52. The inner wall of the first assembly space 31 and the bottom wall of the other end of the first push rod 71 opposite to the end with the first installation notch 710 form the first enclosed space 32. One end of the first spring 74 can be connected to the inner bottom wall of the first installation notch 710, and the other end of the first spring 74 can be connected to the side wall of the first connecting member 72.

[0112] With such arrangement, when the temperature rises, the first expansion medium 33 expands and becomes larger, and the pressure difference between the first assembly space 31 and the first stopping space 53 generates a thrust to push the first push rod 71 to move along the first assembly space 31 in the direction of the first stopping hole 52, thereby driving the first connecting member 72 to enter the first stopping space 53 through the first stopping hole 52. When the first connecting member 72 completely enters the first stopping space 53, the first connecting member 72 rotates around the first rotating axis 73 toward the side of the first stopping portion 51 close to the first stopping space 53 under the action of the restoring force of the first spring 74. When the temperature drops, the first expansion medium 33 contracts, and the pressure difference between the first assembly space 31 and the first stop space 53 generates thrust to push the first connection mechanism 70 toward the first assembly space 31 until the first connection mechanism 70 is completely accommodated in the first assembly space 31, driving the first connection member 72 to rotate around the first rotation axis 73 away from the first stop portion 51 and close to the first stop space 53, and can be moved back to the first assembly space 31 to disconnect the assembly box 10 and the modular mold 21. Compared with common connection methods such as snap connection, bolt connection and threaded connection, the first connection mechanism 70 can cooperate with the preheating and cooling process of the eyeglass frame molding mold 100 to achieve the connection and disconnection of the assembly box 10 and the mold modular component 20.

[0113] Optionally, in some embodiments, see Figure 4 , Figure 7 , Fig.12 and Fig.13 The second connecting mechanism 80 includes a second push rod 81 , a second rotating shaft 83 , a second connecting member 82 and a second spring 84 .

[0114] One end of the second push rod 81 is movably arranged in the second assembly space 41, and a second enclosed space 42 is formed between the inner wall of the second assembly space 41 and the second push rod 81; the other end of the second push rod 81 is provided with a second installation notch 810, and the second installation notch 810 passes through the end face and at least one side face of the second push rod 81.

[0115] The second rotating shaft 83 is located in the second installation notch 810 and connected to the inner wall of the second installation notch 810 .

[0116] One end of the second connecting member 82 is rotatably connected to the second push rod 81 via a second rotating shaft 83 .

[0117] One end of the second spring 84 is connected to the second push rod 81 , and the other end of the second spring 84 is connected to the second connecting member 82 .

[0118] Among them, the second connecting member 82 can be inserted into the second locking hole 62 and extend into the second locking space 63, and under the action of the second spring 84, it rotates to abut against the side of the second locking portion 61 close to the second locking space 63, so that the second connecting mechanism 80 and the second connecting portion 60 can be detachably connected.

[0119] It can be understood that the cooperation between the second push rod 81 and the second assembly space 41 can be a transitional cooperation, and the second push rod 81 moves along the second assembly space 41 in the direction toward the second stop hole 62. The inner wall of the second assembly space 41 and the bottom wall of the other end of the second push rod 81 opposite to the end with the second installation notch 810 form a second enclosed space 42. One end of the second spring 84 is connected to the inner bottom wall of the second installation notch 810, and the other end of the second spring 84 is connected to the side wall of the second connecting member 82.

[0120] With such a configuration, when the temperature rises, the second expansion medium 43 expands and becomes larger, and the pressure difference between the second assembly space 41 and the second stop space 63 generates a thrust to push the second push rod 81 to move along the second assembly space 41 in the direction toward the second stop hole 62, driving the second connecting member 82 to enter the second stop space 63 through the second stop hole 62. When the second connecting member 82 completely enters the second stop space 63, the second connecting member 82 rotates around the second rotation axis 83 toward the second stop portion 61 close to the second stop space 63 under the action of the restoring force of the second spring 84. When the temperature drops, the second expansion medium 43 contracts, and the pressure difference between the second assembly space 41 and the second stop space 63 generates a thrust to push the second push rod 81 to move toward the second assembly space 41, driving the second connecting member 82 to rotate around the second rotation axis 83 and the second stop portion 61 close to the other side of the second stop space 63. Compared with common connection methods such as snap connection, bolt connection and threaded connection, the second connection mechanism 80 can cooperate with the preheating and cooling processes of the eyeglass frame forming mold 100 to achieve the connection and disconnection between the assembly box 10 and the mold modular component 20.

[0121] Optionally, see Figure 5 and Figures 9 to 11 A first spring mounting hole 711 is formed on the inner bottom wall of the first mounting notch 710 , and the opening of the first spring mounting hole 711 faces the first locking space 53 , and one end of the first spring 74 is disposed in the first spring mounting hole 711 .

[0122] It can be understood that when the assembly box 10 and the modular mold 21 are connected through the first connection mechanism 70, the first spring 74 is completely accommodated in the first spring installation hole 711. When the first connection mechanism 70 disconnects the assembly box 10 and the modular mold 21, the first spring 74 is pulled up and extends into the first installation notch 710.

[0123] In this way, by arranging the first spring 74 in the first spring mounting hole 711, the first spring 74 can be completely accommodated in the first spring mounting hole 711 when the first connecting mechanism 70 plays a connecting role, so that the first connecting member 72 can abut against the side of the first stop portion 51 close to the first stop space 53. Compared with the case where the first spring mounting hole 711 is not provided, the first connecting member 72 can abut against the side of the first stop portion 51 close to the first stop space 53, increase the rotation angle of the first connecting member 72, and make the connection tighter. At the same time, the stability of the installation of the first spring 74 can be enhanced.

[0124] Optionally, see Figure 7 , Fig.12 and Fig.13 A second spring mounting hole 811 is formed on the inner bottom wall of the second mounting notch 810 , and the opening of the second spring mounting hole 811 faces the second locking space 63 , and one end of the second spring 84 is disposed in the second spring mounting hole 811 .

[0125] It can be understood that when the modular molds 21 are connected by the second connection mechanism 80, the second spring 84 is completely accommodated in the second spring installation hole 811. When the second connection mechanism 80 disconnects the modular molds 21, the second spring 84 is pulled up and extends into the second installation notch 810.

[0126] In this way, by arranging the second spring 84 in the second spring mounting hole 811, the second spring 84 can be completely accommodated in the second spring mounting hole 811 when the second connecting mechanism 80 plays a connecting role, so that the second connecting member 82 can abut against the two sides of the second stop portion 61 close to the second stop space 63. Compared with the case where the second spring mounting hole 811 is not provided, the second connecting member 82 can abut against the side of the second stop portion 61 close to the second stop space 63, increase the rotation angle of the second connecting member 82, and make the connection tighter. At the same time, the stability of the installation of the second spring 84 can be enhanced.

[0127] For example, see Figure 5 and Figures 9 to 11 The number of the first springs 74 includes at least two, and the first connecting member 72 includes a first connecting rod 720 and a second connecting rod 721 .

[0128] The first connecting rod 720 and the first push rod 71 are connected via a first rotating shaft 73 , and one side of the first connecting rod 720 is connected to the first push rod 71 via one of the first springs 74 .

[0129] The second connecting rod 721 and the first push rod 71 are connected via a first rotating shaft 73 , and one side of the second connecting rod 721 is connected to the first push rod 71 via another first spring 74 .

[0130] The first connecting rod 720 and the second connecting rod 721 can be inserted into the first locking hole 52 and extend into the first locking space 53, and rotate relatively away from each other under the action of the two first springs 74 until they abut against the side of the first locking portion 51 close to the first locking space 53, so that the first connecting mechanism 70 and the first connecting portion 50 are detachably connected;

[0131] It can be understood that the side wall of the first connecting member 72 close to the first locking portion 51 is connected to the first spring 74 .

[0132] In this way, the first connecting member 72 includes a first connecting rod 720 and a second connecting rod 721. Compared with the first connecting member 72 with a single connecting rod, the first connecting member 72 with two or more connecting rods can share the pressure of the single connecting rod, can protect the first connecting rod 720, and improve the reliability of the connection between the assembly box 10 and the modular mold 21.

[0133] For example, see Figure 7 , Fig.12 and Fig.13 , the number of the second springs 84 includes at least two, the number of the second springs 84 is at least two; the second connecting member 82 includes a third connecting rod 820 and a fourth connecting rod 821.

[0134] The third connecting rod 820 and the second push rod 81 are connected via the second rotating shaft 83 , and one side of the third connecting rod 820 is connected to the second push rod 81 via one of the second springs 84 .

[0135] The fourth connecting rod 821 and the second push rod 81 are connected via a second rotating shaft 83 , and one side of the fourth connecting rod 821 is connected to the second push rod 81 via another second spring 84 .

[0136] Among them, the third connecting rod 820 and the fourth connecting rod 821 can be inserted into the second locking hole 62 and extend into the second locking space 63, and under the action of the two second springs 84, they can rotate relatively away from each other until they abut against the side of the second locking portion 61 close to the second locking space 63, so that the second connecting mechanism 80 and the second connecting portion 60 can be detachably connected.

[0137] It can be understood that the side wall of the second connecting member 82 close to the second locking portion 61 is connected to the second spring 84 .

[0138] In this way, the second connecting member 82 includes a third connecting rod 820 and a fourth connecting rod 821. Compared with the third connecting rod 820 having a single connecting rod, the second connecting member 82 having two or more connecting rods can share the pressure of the single connecting rod and protect the third connecting rod 820.

[0139] In some embodiments, see Figures 3 to 5 A first reinforcement structure 712 is provided on the side of the first push rod 71; a first installation space 513 is opened on the inner side wall of the first locking hole 52, and the first connecting part 50 also includes a first movable reinforcement block 511, which is movably arranged in the first installation space 513, and a third enclosed space 510 is formed between the first movable reinforcement block 511 and the inner wall of the first installation space 513, and a third expansion medium 512 is provided in the third enclosed space 510. The third expansion medium 512 is used to expand and expand when the temperature rises, and push the first movable reinforcement block 511 to partially extend into the first locking hole 52 to engage with the first reinforcement structure 712, and to shrink and shrink when the temperature drops, and drive the first movable reinforcement block 511 to retract into the first installation space 513, so that the first movable reinforcement block 511 is separated from the first reinforcement structure 712.

[0140] It can be understood that the first reinforcement structure 712 can be set as a protruding block and a groove structure. The first movable reinforcement block 511 can move along the first installation space 513 to the side wall direction of the first push rod 71 close to the first installation space 513. The bottom wall of the first movable reinforcement block 511 close to the bottom wall of the first installation space 513 and the inner wall of the first installation space 513 form a third closed space 510, and the vaporization point of the third expansion medium 512 is higher than the normal temperature (20 to 25 degrees Celsius) and lower than the temperature of the injection liquid (for example: the temperature range of polycarbonate (PC) during injection molding is 250 to 320 degrees Celsius).

[0141] In this arrangement, when the assembly box 10 and the modular mold 21 are connected via the first connecting mechanism 70, the first reinforcement structure 712 cooperates with the first installation space 513, and the first movable reinforcement block 511 and the first reinforcement structure 712 abut against each other to clamp the first push rod 71, so as to reinforce the first connecting mechanism 70 and prevent the connection of the first connecting mechanism 70 from falling off.

[0142] In some embodiments, see Figures 4 to 7A second reinforcement structure 812 is provided on the side of the second push rod 81; a second installation space 613 is opened on the inner side wall of the second locking hole 62, and the second connecting part 60 also includes a second movable reinforcement block 611, which is movably arranged in the second installation space 613, and a fourth enclosed space 610 is formed between the second movable reinforcement block 611 and the inner wall of the second installation space 613. A fourth expansion medium 612 is provided in the fourth enclosed space 610, and the fourth expansion medium 612 is used to expand and expand when the temperature rises, and push the second movable reinforcement block 611 to extend into the second locking hole 62 to engage with the second reinforcement structure 812, and to shrink and shrink when the temperature drops, and drive the second movable reinforcement block 611 to retract into the second installation space 613, so that the second movable reinforcement block 611 is separated from the second reinforcement structure 812.

[0143] It is understood that the second reinforcement structure 812 can be set as a protruding block and a groove structure. The second movable reinforcement block 611 can move along the second installation space 613 to the side wall direction of the second push rod 81 close to the second installation space 613. The bottom wall of the second movable reinforcement block 611 close to the bottom wall of the second installation space 613 and the inner wall of the second installation space 613 form a fourth closed space 610, and the vaporization point of the fourth expansion medium 612 is higher than the normal temperature (20 to 25 degrees Celsius) and lower than the temperature of the injection liquid (for example: the temperature range of polycarbonate (PC) during injection molding is 250 to 320 degrees Celsius).

[0144] With such an arrangement, when each modular mold 21 is connected via the second connecting mechanism 80, the second reinforcement structure 812 cooperates with the second installation space 613, and the second movable reinforcement block 611 and the second reinforcement structure 812 abut against each other to clamp the second push rod 81, so as to reinforce the second connecting mechanism 80 and prevent the connection of the second connecting mechanism 80 from falling off.

[0145] Optionally, in some embodiments, see Figure 1 and Fig.12 , one of the modular molds 21 is a glasses frame mold 22, and the glasses frame mold 22 has a first cavity 220 for forming a glasses frame;

[0146] Another modular mold 21 is a temple mold 25, and the temple mold 25 has a second cavity 250 for forming the temple;

[0147] The eyeglass frame mold 22 is detachably connected to the eyeglass leg mold 25 via the second connecting mechanism 80 .

[0148] With such arrangement, different eyeglass frame molds 22 and eyeglass leg molds 25 are matched and linked to form different eyeglass frame forming molds 100 to meet the demand for producing different eyeglass frame forming molds 100 .

[0149] Optionally, see Figure 1 and Figure 2 The eyeglass frame mold 22 has a main connecting channel 221 and a first secondary connecting channel 222, and the main connecting channel 221 and the first cavity 220 are connected through the first secondary connecting channel 222; the eyeglass leg mold 25 has a second secondary connecting channel 251, and the second cavity 250 and the main connecting channel 221 are connected through the second secondary connecting channel 251.

[0150] It can be understood that the main communication channel 221, the first secondary communication channel 222 and the second secondary communication channel 251 can be set as circular channels, triangular channels, square channels, etc.

[0151] In this configuration, the main communication channel 221 is connected to the eyeglass frame mold 22 via the first secondary communication channel 222, and the main communication channel 221 is connected to the eyeglass leg mold 25 via the second secondary communication channel 251. Compared with the eyeglass frame molding mold 100 without communication channels, the injection molding device can perform injection molding at a fixed position of the main communication channel 221.

[0152] In some embodiments, see Figure 1 and Figure 7 The glasses frame mold 22 includes a glasses outer frame mold 23 and a glasses inner frame mold 24 . The glasses outer frame mold 23 is provided with a second space 230 . The glasses inner frame mold 24 can be detachably installed in the second space 230 .

[0153] It can be understood that the second space 230 can completely accommodate the glasses inner frame mold 24 , and the glasses inner frame mold 24 is detachably installed in the second space 230 via the second connecting mechanism 80 .

[0154] In this way, different glasses inner frame molds 24 are detachably installed in the second space 230, and together with different glasses outer frame molds 23, form a complete glasses frame mold 22. Compared with the integrated glasses frame mold 22, the glasses frame mold 22 including the glasses outer frame mold 23, the glasses inner frame mold 24 and the second connecting mechanism 80 can meet more requirements of the glasses frame mold 22. In addition, the glasses inner frame mold 24 is detachably installed in the second space 230, and the glasses frame can be demoulded after the glasses inner frame mold 24 is removed.

[0155] In some embodiments, see Figure 3The eyeglass frame mold 22 includes an eyeglass frame mold body 223, a first movable cavity block 224 and a first adjustment block 225. The eyeglass frame mold body 223 has a first cavity 220. The first movable cavity block 224 is disposed in the first cavity 220, and the shape of the first movable cavity block 224 matches the shape of the first cavity 220. A first adjustment hole 226 is provided on the inner side wall of the first cavity 220. The first adjustment block 225 is movably disposed in the first adjustment hole 226. The first adjustment block 225 partially extends into the first cavity 220 and is located between the first movable cavity block 224 and the bottom wall of the first cavity 220. The first adjustment block 225 can move toward the first movable cavity block 224 in the first adjustment hole 226 to drive the first movable cavity block 224 to move along the depth direction of the first cavity 220 away from the bottom wall of the first cavity 220, so that the first movable cavity block 224 drives the molded eyeglass frame to at least partially leave the first cavity 220.

[0156] It can be understood that the cooperation between the first movable cavity block 224 and the first cavity 220 can be a transitional cooperation, and the first movable cavity block 224 is completely contained in the first cavity 220. The first adjustment block 225 can be completely contained in the first adjustment hole 226, and one end of the first adjustment block 225 is provided with an inclined surface, and the outer edge line of the bottom of the first movable cavity block 224 is slidably matched with the inclined surface. Before injection molding, the first adjustment block 225 is adjusted to completely contain the first adjustment hole 226, and the first movable cavity block 224 is at the bottom of the first cavity 220. In the case of cooling molding of the injection liquid, the first adjustment block 225 is adjusted to partially enter the first cavity 220, and the first movable cavity block 224 moves along the depth direction of the first cavity 220 until the eyeglass frame is pushed away from the first cavity 220.

[0157] In this way, the first movable cavity block 224 and the first cavity 220 are set to be transitionally matched, so that the contact between the first movable cavity block 224 and the first cavity 220 is closer, so as to prevent the injection liquid from penetrating into the gap between the first movable cavity block 224 and the first cavity 220. By pushing the first adjustment block 225 to move toward the first cavity 220, the first movable cavity block 224 moves along the depth direction of the first cavity 220 under the action of the inclined surface of the first adjustment block 225, so as to push the eyeglass frame out of the first cavity 220, so as to facilitate the demoulding of the eyeglass frame.

[0158] In some embodiments, see Figure 4The temple mold 25 includes a temple mold body 253, a second movable cavity block 254 and a second adjustment block 255. The temple mold body 253 has a second cavity 250. The second movable cavity block 254 is movably arranged in the second cavity 250, and the shape of the second movable cavity block 254 is adapted to the shape of the second cavity 250. A second adjustment hole 256 is opened on the inner wall of the second cavity 250. The second adjustment block 255 is movably arranged in the second adjustment hole 256. The second adjustment block 255 partially extends into the second cavity 250 and is located between the second movable cavity block 254 and the bottom wall of the second cavity 250. The second adjustment block 255 can move toward the bottom wall of the second movable cavity block 254 in the second adjustment hole 256, so that the second movable cavity block 254 drives the molded temple to at least partially leave the second cavity 250.

[0159] It can be understood that the cooperation between the second movable cavity block 254 and the second cavity 250 can be a transitional cooperation, and the second movable cavity block 254 is completely contained in the second cavity 250. The second adjustment block 255 can be completely contained in the second adjustment hole 256, and one end of the second adjustment block 255 is provided with an inclined surface, and the outer edge line of the bottom of the second movable cavity block 254 is tangent to the inclined surface. Before injection molding, the second adjustment block 255 is adjusted to completely contain the second adjustment hole 256, and the second movable cavity block 254 is at the bottom of the second cavity 250. In the case of cooling molding of the injection liquid, the second adjustment block 255 is adjusted to partially enter the second cavity 250, and the second movable cavity block 254 moves along the depth direction of the second cavity 250 until the temple of the glasses is pushed away from the second cavity 250.

[0160] In this way, the second movable cavity block 254 and the second cavity 250 are set to be transitionally matched, so that the contact between the second movable cavity block 254 and the second cavity 250 is closer, so as to prevent the injection liquid from penetrating into the gap between the second movable cavity block 254 and the second cavity 250. By pushing the second adjustment block 255 to move toward the second cavity 250, the second movable cavity block 254 moves along the depth direction of the second cavity 250 under the action of the inclined surface of the second adjustment block 255, so as to push the eyeglass frame out of the second cavity 250, so as to facilitate the demoulding of the eyeglass legs.

[0161] An embodiment of the present application further provides a spectacle frame manufacturing device, the spectacle frame manufacturing device comprising the spectacle frame forming mold 100 of any of the above embodiments.

[0162] It is understandable that the eyeglass frame manufacturing equipment may also include: an injection molding machine, a mold preheating device, a cooling system, a post-processing device and a testing device. The various parts of the eyeglass frame forming mold 100 are placed in the mold preheating device according to the corresponding positions. The injection molding machine performs injection molding on the cavity of the preheated eyeglass frame forming mold 100, and after the injection molding is completed, the eyeglass frame forming mold 100 is placed in the cooling system. After the injection molding liquid is cooled and molded, the eyeglass frame parts are taken out and placed in the post-processing device, and a complete eyeglass frame is formed after processing. Finally, the eyeglass frame is placed in the testing device to detect whether the eyeglass frame meets the national standards.

[0163] In this way, the spectacle frame forming mold 100 formed by placing the various parts of the spectacle frame forming mold 100 in the corresponding positions is placed in the mold preheating device. When the mold preheating device preheats the spectacle frame forming mold 100, the various parts of the spectacle frame forming mold 100 form an integral spectacle frame forming mold 100; after the preheating is completed, the spectacle frame forming mold 100 is placed in the injection molding position of the injection molding machine, and the cavity of the spectacle frame forming mold 100 is injection molded. The spectacle frame forming mold 100 after injection molding is placed in the cooling system, and the connection of the various parts of the spectacle frame forming mold 100 is disconnected when the injection molding liquid in the cavity of the spectacle frame forming mold 100 is cooled. During the preheating process, the various parts of the spectacle frame forming mold 100 can be automatically connected to form an integral spectacle frame forming mold 100, and when the injection molding liquid is cooled, the various parts of the spectacle frame forming mold 100 are automatically disconnected when the cooling parts are cooled.

[0164] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
